[repost ]How to Autostart an Android Application?


You have to add a manifest permission entry:

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

(of course you should list all other permissions that your app uses).

Then, implement BroadcastReceiver class, it should be simple and fast executable. The best approach is to set an alarm in this receiver to wake up your service (if it’s not necessary to keep it running ale the time as Prahast wrote).

public class BootUpReceiver extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
    AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
    PendingIntent pi = PendingIntent.getService(context, 0, new Intent(context, MyService.class), PendingIntent.FLAG_UPDATE_CURRENT);
    am.setInexactRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + interval, interval, pi);

Then, add a Receiver class to your manifest file:

    <receiver android:enabled="true" android:name=".receivers.BootUpReceiver"
            <action android:name="android.intent.action.BOOT_COMPLETED" />
            <category android:name="android.intent.category.DEFAULT" />

If by autostart you mean auto start on phone bootup then you should register a BroadcastReceiver for the BOOT_COMPLETED Intent. Android systems broadcasts that intent once boot is completed.

Once you receive that intent you can launch a Service that can do whatever you want to do.

Keep note though that having a Service running all the time on the phone is generally a bad idea as it eats up system resources even when it is idle. You should launch your Service / application only when needed and then stop it when not required.
